This Model Is Fully Compliant With UK Road Regulations
This bike is built to comply with UK Electrically Assisted Pedal Cycle (EAPC) regulations, meaning it can be used on public roads and cycle paths without registration, tax, or a licence. Motor assistance is limited to 250W and cuts off at 15.5 mph (25 km/h).
See UK LegislationThe maker quotes 31 mi; in mixed riding with some hills, expect nearer 23 mi. Everything here is worked out from this bike's own specification. Estimates, not promises: the assumptions are printed underneath.
Range you can expect
| Low assist, flat roads | 31 mi |
|---|---|
| Mixed riding, some hills | 23 mi |
| Full assist, loaded or hilly | 17 mi |
| Riding time on a charge | 2 h |
Sixteen-inch wheels with three-inch tyres, for £589
The Koolux X10 runs 16 × 3 inch tyres, folds, and claims 31 to 40 miles, at £589.
250W and 15.5 mph: it meets the EAPC rules, so there is no licence, no tax and no registration.
Sixteen inches with three inches of tyre
That is an uncommon pairing: a small wheel, but a wide tyre on it.
- The small wheel gives a compact folded size
- The wide tyre recovers the comfort a small wheel loses
- Three inches takes a paving edge a thin tyre would pass into your hands
- And the whole thing stays within the rules
Thirty-one miles from a 13Ah battery
Koolux claims 31 to 40 miles and our table carries the lower figure.
This is a bike for short trips: station to office, car park to town centre. The panel below turns the capacity into energy per mile so you can see what that really means rather than take the headline on trust.
Koolux publishes four rows, and we will not fill in the rest
The sheet for this model runs to four lines: power, speed, range and wheel size. There is no weight, no payload, no brake type, no charging time and no frame material.
The table below leaves all of those empty rather than filling them in on a guess. On a folding bike the payload is the row that matters most, because the hinge is what sets it. Write to us before you order and we will chase Koolux for the answer.
Before the first ride
It arrives folded and nearly built.
- Unfold and lock the frame and the stem, then check both again after the first hour
- Bed the brakes in at walking pace before the first city ride
- Inflate both tyres: a small wheel loses pressure faster than a large one
- Set the saddle before you set off
- Charge it fully before the first ride
Who it is for
Someone who combines the bike with a train, a bus or a car, and who wants more comfort than a thin-tyred folder gives.
Buy it for the folded size and the three inches of tyre. If you ride more than thirty miles at a stretch or carry weight, write to us: our 20-inch folders with larger batteries are better placed.

3 of 7 specifications differ. View DYU A1F Electric Folding Bike
- Are the electric bikes brand new?
- Yes. All electric bikes sold by BikTron are brand new, factory-sealed, and sourced directly from authorised manufacturers and official distributors.
- How do I choose the right electric bike for me?
- Pick a bike based on how you plan to ride. City bikes are great for commuting, folding bikes work well if you need compact storage, mountain bikes handle hills and mixed terrain, and cargo bikes are ideal for carrying shopping or loads. If you are not sure, our Bike Quiz can help.
- Are the batteries original and certified?
- Yes. Every electric bike battery is brand new and original from the manufacturer, with full safety certification and performance testing.
- Are the bikes tested before shipping?
- Yes. Each e-bike goes through a quality check before dispatch, covering electronics, brakes, motor response, and battery performance.
- Do electric bikes come with a warranty?
- Yes. All electric bikes from BikTron include a manufacturer warranty. Duration depends on the brand and model. Most bikes include a 12-month warranty as standard.
- How long does delivery take?
- Standard UK delivery usually takes 2 to 7 business days. Remote areas may take a little longer. You will receive a tracking link by email once your order is dispatched.
- Which payment methods do you accept?
- We accept Visa, Mastercard, PayPal, Apple Pay, Google Pay, and Klarna buy-now-pay-later. All payments are processed securely.
- Can I return my electric bike?
- Yes. You can ride the bike and still return it. Tell us within 30 days of delivery and we book the courier and collect it from your door. Contact us first and we will guide you through the process.
- Do the bikes need assembly?
- Most electric bikes arrive 85 to 90 per cent pre-assembled. You will usually need to attach the handlebars, pedals, and adjust the seat. A basic tool set is often included.
- Are BikTron electric bikes legal to ride in the UK?
- Yes. All bikes sold by BikTron that meet UK EAPC rules (250W motor, max 15.5 mph assisted speed, pedal-assisted only) are fully road-legal. You do not need a licence, tax, or insurance to ride them on public roads. Riders must be at least 14 years old.
- What about the electric scooters?
- Those are different, and the law treats them differently. A privately owned e-scooter cannot legally be ridden on a public road, pavement or cycle lane in the UK, whoever sold it. We sell ours for private land use only, with the landowner's permission, and every scooter product page says so. If you want something you can ride to work, choose an electric bike.
